PROCESS OF AND APPARATUS FOR POP PING 0R BURSTING BARLEY, 8L0.

SPEGIFIGATION forming part of Letters Patent vN 0. 508,125, dated November '7, 1893.

Application filed October 2, 1893. $erial No. 487,042.

To all whom it may concern:

Be it known that I, JAMES WHITE, of London, England, have invented acertain new and useful Process of and Apparatus for Popping or BurstingBarley, Maize, or other Grain, (for which I have obtained a patent inGreat Britain, No. 21,632, bearing date November 26, 1892,) of which thefollowing is a specification.

This invention has reference to the popping maize or other grain. In theprocess or method which has hitherto been generally adopted the poppingor bursting of grain is effected by bringing hot airor fumes into directcontact with the grain while this is caused to travel down an inclinedrotating wire woven or foraminous cylinder or other carrier or conveyer.In such process the grain isliable to become burned by direct contactwith the-hot air orproducts; further the popping or bursting issometimes imperfect or irregular.

Now my invention relates to an improved process or method and apparatuswhereby all liability of the grain to get burned during the popping orbursting process is prevented.

My process or method consists in submitting the grain to be popped orburst to the s1- multaneous action of hot air or hot fumes brought intodirect contact with said grain and of jets of steam also broughtintodirect contact with said grain when traveling down the inner surfaceof an inclined rotating wire woven or foraminous cylinder, or othersuit-- able carrier or conveyor such for example as a vibrating plate ina hot chamber. The steam thus applied to the grain simultaneously withthe hot air or fumes prevents the grain from becoming burned by thehotair or fumes and has the further advantage of causing the grain to popor burst more thoroughly and uniformly.

As regards my improved apparatus the invention consists in thecombination with an inclined rotating wire woven or foraminous cylinderor other carrier or conveyor to which the grain to be treated is fed andalong which it travels and a hot chamber within which said carrier isplaced, of a series of nozzles to discharge steam directly upon thegrain while passing down said carrier.

'half their length more or less.

(No model.) Patented in England November 26, 1892, No. 21,632.

In the accompanying drawings:Figure 1 is a longitudinal section on theline 11 of Fig. 2 of an apparatus constructed according to my inventionwhen applied in connection with a series of grain conveyers in the formof an inclined rotating foraminous cylinder. Fig. 2 is a section of theapparatus on the broken line- 22 of Fig. 1, looking in the direction ofthe arrow 00.

In the drawings or represents a hot chamber which is shown as heated bymeans of direct fumes from a fire at b but any other means of heating iteither by direct fumes, or by hot air can be adopted.

0 is a chimney or outlet to the chamber. at d are wire woven or otherforaminous inclined cylinders the shafts e of which are.

mounted in bearings at ff in the end walls of the chamber a.

g g is bevel gearing by which rotary motion is transmitted to thecylinders cl from a shaft h driven by a belt 2' and pulley Zr. It isobvious that any other suitable means for transmitting rotary motion tothe cylinders can be adopted such for example as a pulley on the shaft'6 of each cylinder driven by a belt from any available source of power.Each cylinder d is fitted with a feed chuteZ supplied with grain from ahopper (not shown) or otherwise and each cylinder at is also fitted witha discharge chute m.

'n n are steam pipes extending externally along the lower parts of thesides of the cylinders d from the bottom end of same for about Thesepipes not are supplied with steam from a pipe 19 and are each fittedwith nozzles q q the outlets or mouths of which are directed toward thecylinders so as to discharge steam against and through their foraminoussurface.

When the apparatus is in use the grain entering the upper end of eachrotating foraminous cylinder (1 from the feed chute Ztravels down thecylinder, being continually turned over by the rotation of saidcylinder, and on reaching the lower end it falls into the dischargechute m. During its passage down the cylinder the grain is heated by thehot fumes which tend to pop or burst it; but by the time it has passeddown about one half more or less of the cylinder theheat is liable toburn ICO What I e mmd de e t ecu e y L t ters Patent, is-- 1. Theprocess or method of popping or i bursting barley, maize or other grain,which onsists in Submitting the gra t the simulaham a ion f h fumes 91't a and of ee hiele ro ht in d ect cement w th he gra whe t a e ng d n acar r s ah ia l as and for the pu p s e forth- I apparatu o popp es n ht ngbara m le or h r g ain, the combi a i n of l a ear ie ale s whi h hgra t av s, a hot chamber containing said carrier, and. a series ofnozzles todischarge steam directly upon the grain while traveling alongsaid carrier, substantially as and for the purpose set forth.

3. In apparatus for popping or bursting barley, maize or other grain,the combination of a rotating foraminous inclined cylinder along whichthe grain travels, a hot chamber containing said cylinder and a seriesof nozzles to discharge steam directly upon the grain while travelingalong said cylinder, substantially as and for the purpose set forth.
